rpplicution filed May 13., 1922.

To all whom, z' may con-cem:

Be it known that ANnREW C. ivoor), a citizen of the United States, residing in the city of Chicago, in the county of Cook and the State ot' Illinois, have invented certain new and useful Improvements in Vacuum Fuel-Feed Reserve Systems, of which the following is :i specification, reference being had to the ecconumnying drawings, forminfr e part thereof.

The purpose o? this invention is to provide un improved construction of e vacuum fuel feeding device having means for providing a reserve supply ot fuei to he drawn upon in case of emergency, as when the main supply tank is exhausted or when the requirements of the curliureter exceeds the capacity of the emptying devices for lifting from the low tank to the supply receptacle, or when said supply devices are for any reason temporarily inoperative, and incidentally providing for straining the fuel. It consists in the elements und features of construction shown and described, es indicated in the claims.

In the drewings:-

Figure 1 is a'vertical axial section of e vacuum fuel feed device equipped with the features constituting this invention.

Figure 2 is e similar'view of u modified form.

Figures 3, 4, 5 end-6 are axiui sections of a valve for controlling the delivery to the carbureter from the ordinary supply or from the reserve supply er from both.

Figure 7 is a, diagrammatic view showing .the device mounted in e position of service on the car in its relation es to the engine and as to the car, end operating devices extendingto the dasi The structure shown in the drawings comprises a, usuel form of vacuum fuel feeding device haring e vacuum chamber, l, with suction connections, la, atmosphereinlet, 1b, fuel supply connections, itc, and Hoet-controlled ,vulve mechanism, A, oper ated b v e Hoet, 4:, in e manner Weil und-en stood for alternating the dominance of snction' and atmospheric pressure for eiternately lifting the fuei rontreA-iorvsource not shown, to the`vacui1he-'.ehie.hhir, i, and delivering it by grevity froririithe ymciuiro. chamber to the ordinary carhlireter suppiy chamber, 2, past the nonreturn check valve., 5. In addition to these familiar features of Serial No. 580,090.

n i n vacuum fuel feed devices the present invention comprises e. third clizim'ocr, Si, which is shown in Figur-e l encompassing the chem lier.J F3, :md communicating' therewith et. e ier i. considerabl f above the bottom ot both chznnhers, es :it the itiltciscieened freer-y tures, 2, in the well. et the chemin., which utthis part is u partition wzili between the clunnbers. und 3. Each of the chambers, Q and 3, has :L discharge connection for supplying the curbineter, being the pipe, i', lending' 'from the cheminer, f?, and. the pipe. 8 leading; from the chamber, 2S, Preferably these two pipes ere connec i, ns et the eim-ittingr, 9 forming u junction oc-tween them. This 'itittingi is the body or u threewey vaive, seen in Figure G, and is hereinafter referred to es the vulve body, i). This valve hodyihns three pew sages, Si, Si", 9", for connecting respectively, with the curhureter, with the chmnher. 2, and with the chamber, 3; and the or turn-cock member or valve proper, 1G, has a diumetric passage, 10a, and :l` redini passage, 10, vv'lzerelryy it is adapted to be sett as seen in Figure 3 for comiuunicziticn.

The operating stein, 1i. of the mirc mem her, l0, is coniiectcd ttor operation by the driver at the dash or instrument heard, es indicated in Figure '7, h v the extension, i?, of the stem coilnected with the stein proper hy a toggle joinnas seen :it 1 3. ist the dash board or instrument board, the .stun extension, 12hes operating handie in the form ot u knob, ifi, and en index finger, 14a, which cooperates with en index piate, it, havingmericinge to indica-te 'thethree adjustments of the wives, respec tively, so that the driver' muy et xviii ed just so to the carhureter supply,- ztrom the chamber, 2, 3, or fromfooth said chambers, simuiteneousiv according to the conditions.

The form shown in Figure i?, differs from the forni shown in, Fie-nre it, in that the direct und immediate uischerge from vacuum chamber, i, into the outer ins. et into the inner of the other tivo chambers. This eccompiished by inenting the veive,
